My dad's IH 300 Utility gas started running rough and pouring black smoke. Figured the float valve needed replacing as it sounded like it was flooding. Did a carb rebuild and still did the same. When you turn the fuel off, a few seconds before it dies it begins to run perfect. So I took the carb off again and thought maybe the float needs to be set lower to lower the fuel level.

The points didn't look burned but I cleaned them with a dollar bill anyhow. And they look like they are gapped properly.
